New test data
This is with Park 370 outrunners spinning 9x7x3 MAS counter-rotating props on 18 amp CC esc's powered by 1 - TP 3s 2100

Static WOT
combined watts as read by e-flite wattmeter:
250 watts on fresh charged battery
239 watts after run down on battery to about 11.5 volts
218 watts after voltage dropped to below 11
Amp draw 23.5
Pretty much what I expected after doing single motor tests at about 145 watts per motor. A slight drop of 20 watts per motor when two in use off of same battery.
Mind you it takes quite awile to run down the battery, but I can get a sense that its getting close to below 11v and better bring it in for landing to avoid hitting LVC, but this would be imprecsise at I will still fo course use a timer.

One thing I do have to say though, is that I think tis best to get slightly bigger diameter foam wheels if using 9inch diameter props. There is clearance with the stock wheels, but if you come in for a landing nose down slightly, you will strike the ground with the props(if using 3 -blade). 2 bladers may simply align themselves out of the way. Anyhow, I will pick up some foam 2.5 inch wheels and use one of the stock main wheels for the nose.
